ive just upgraded my tiscali broadband from 2mb to 8 mb, but ever since ive had problems,ever time i use the phone i get internet explorer cannot display the webpage and the only way i can get back onto a webpage is to reset the modem(sagem 800).ive tried using a different phone and new filter but it makes no difference.ive had 5 long phone calls to tiscali but problem still not resolved.
ive re-installed the modem still no difference,when i ping the ip address it come back with timed out,can you help,starting to get very fustrating.

Classic sign of bad interior wiring, bad filters, or marginal lines from the ISP. You can address interior wiring issues, but if that doesn't fix it, you'll have to get Tiscali in the picture.

My fix for DSL/ADSL interior wiring issues.

Purchase a DSL splitter and install it at the telco service entrance. Run a direct line from the DSL port on the splitter directly to the DSL modem. Connect all of the other phone instruments to the telephone output of the DSL splitter. All of the DSL analog side wiring should be CAT3 or better twisted pair from the telco service entrance to the DSL/ADSL modem. You can use one of the twisted pairs in CAT5 cable if you have that on hand.

This is as good as it gets for DSL installations, and will usually solve in-house wiring issues.

Here's a good detailed description of the process: DSL Wiring Upgrade Tutorial

bit confused i dont have a phone box or nid,just the little white box that the phone plugs into is this the same

[JohnWill]

Oh, you have all that other stuff, the "little white box" is connected to something to make the phone work.

[numbnuts1]

yes the wire goes outside and straight to the telegraph pole.do i need to climb up it

[JohnWill]

You have no interface junction box on the house at all? That would be a first, and I'm sorry if I just don't believe that they run a wire from the pole, through the wall, and directly to your modem jack with no junctions. That's just not the way utilities operate.

[numbnuts1]

all i have is the cable coming from the pole into my house and into i a white box that the phone plugs into it has 2 screws in it so you can take the bottom part off so as to get to the main bt line

[JohnWill]

That is the NID (network interface device). If the wire runs right to your modem from that box and nowhere else, I'd consider trying a new wire or bypassing it as a test. If there are no phone instruments connected to the line, what is the discussions about phones and DSL all about? The modem and phone are connected to the one and only jack?

[numbnuts1]

yes thats right the phone and modem are connected to the one jack through a filter and theres no problem until i use the phone.

[JohnWill]

Either there is a problem with the wire from the NID, the filter is bad, or it's installed incorrectly. Remember, the phone is filtered, the DSL modem is NOT.

The other possibility is the ISP has a problem like marginal signal levels, and the phone use pushes it over the edge.
